Memory Game Waves definitionsOnline version match the term to the definition by Dilini Wijayasinghe 1 wave produced by the source per second Waves, of which the particles oscillate perpendicular to the energy Distance moved my energy of the wave in a unit time Wave, of which the particles oscillate parallel to the energy The distance moved by the particle in a particular direction from the equilibrium point An imaginary line drown through the crest of a wave perpendicular to the energy flow Waves which transfer energy The time taken by a source to produce one wave Angle subtended at the centre of a circle when the path of an oscillating particle of a wave is represented by the circumference of the circle. The length between two similar points in two consecutive waves The number of waves produced per unit time by a source Maximum displacement of a particle from the equilibrium point
